How this service works
Pay-per-call data and tools for AI agents, $0.002-0.01 per call in USDC via x402 (Base, Polygon or Solana), no account or API key; MAX tiers ($0.05-0.25) run deeper jobs. Agent toolkit: web search, search + read top pages, any page as clean markdown with a prompt-injection check, which-x402-API-to-call recommender, seller check. Data: Google Maps places with contacts, YouTube video data and transcripts, job listings (Indeed, LinkedIn, 13 boards), Google Ads Transparency, TikTok comments, Pinterest, Airbnb, Redfin, AliExpress, app stores, live sports, website and SEO checks, Shopify store tech stacks, and onchain token / address risk checks.
Output
A paginated list of USDC payment events for the given Base address, each including direction (in/out), amount, timestamp, counterparty, and — where the payment is an x402 transaction — the associated Bazaar seller/listing label. Also returns a cursor value to use in the next poll for incremental updates.
Example use cases
Real-time agent wallet monitoring
“Keep an eye on my agent's Base wallet 0xDeF456... and let me know about any new USDC payments since the last time you checked — especially any that came from x402 sellers.”
Reconcile Bazaar x402 revenue
“Pull all incoming USDC payments for 0x789Ghi... since 2024-06-01T00:00:00Z and tell me which ones are labeled as x402 Bazaar seller transactions so I can reconcile my revenue.”
Audit outgoing agent spending
“Show me up to 100 USDC payment events going out from 0xJkL012... since 2024-07-15T12:00:00Z so I can audit what my agent has been spending on.”
Technical details
Endpoint
GEThttps://agent-data.centorprat.workers.dev/agent/payments-feed?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a real-time, cursor-based incremental feed of USDC payments for a specific Base address, especially when tracking x402/Bazaar seller payments. It is ideal for agent wallets that need to react to new payments without re-processing historical data. Prefer it over general blockchain explorers when you need x402 seller labeling out of the box and low-latency polling via cursor.
Side effects
- Missing or invalid Base address returns a validation error
- Invalid ISO cursor format causes a parsing error or returns all events
- Limit outside 1-200 range returns a validation error
- Address with no USDC activity returns an empty event list
- Network or worker downtime returns a 5xx error
